The biggest single safety upgrade your home can have, a modern consumer unit with RCD and surge protection, fitted in a day at a fixed price.
Your consumer unit, the fuse box, is your home’s electrical safety system. Everything every circuit does passes through it, and everything modern boards do to protect your family, old boards simply don’t. If yours still has rewireable fuses, a wooden backboard or no RCD protection, replacing it is not cosmetic: it’s the difference between a fault tripping a breaker in milliseconds and a fault starting a fire.
Strong signs it's time
(Fuse wire you replace by hand) — decades obsolete.
The trip-switches that cut power fast enough to prevent fatal shock.
Pre-dating modern fire containment rules.
Nowhere to add the EV charger, garden office or kitchen circuit you’re planning.
Against the board, common on surveys and landlord inspections.
Sometimes the board itself, not the circuits.
Modern RCBO boards protect each circuit individually, a fault in the garden doesn’t black out the freezer, and every circuit gets life-saving residual current protection.
Now standard under BS 7671: an SPD absorbs voltage spikes from the grid or nearby lightning that would otherwise quietly destroy the electronics in your boilers, TVs and computers.
Non-combustible metal enclosures, proper labelling of every circuit, and spare capacity for whatever your home does next.
RCBOs – These give each circuit its own combined trip (best practice; slightly dearer than shared “dual RCD” boards, far more convenient).
SPDs – Protect against voltage surges.
AFDDs – Arc fault detection, the newest layer, sensing the electrical “crackle” of a failing connection; required in some higher-risk buildings and worthwhile in others.
Send a photo of your current board through the quote form, most homes can be priced from it.
Board specification, price, and how long you’ll be without power (typically 4–6 hours).
Old unit out, new unit in, every circuit tested to BS 7671 as it’s reconnected — a mini health-check of your whole installation.
An Electrical Installation Certificate and Building Regulations notification, plus a labelled board so you know what everything does.
Fixed prices honoured, registered installers, and a 12-month guarantee. It’s a one-day job for us and a 25-year decision for you, we treat it with that weight.
Most swaps take 4–6 hours including the testing. You’ll be without power for part of that, we’ll agree timing so it never catches you out.
Usually the observation is genuine (no RCDs is a real C2), but we’re happy to review your report free and tell you plainly what’s required versus recommended.
Dual-RCD boards group circuits under two shared trips, one fault can down half the house. RCBO boards trip only the faulty circuit. We fit RCBO as standard because the day something trips, you’ll care.
BS 7671 now expects SPDs in most new boards, and given what a Surrey home carries in electronics, it’s the cheapest insurance you’ll ever buy. Included in our standard price.
Yes. The only extras possible are pre-existing circuit faults revealed by testing, which we quote and you approve before any further work.
Every way, clearly, and we’ll walk you round the board before we leave.
